Application filed December 4, 1908. Serial No. 465,965.

all whom it may concern:

Be it known that we, ROBERT EiFnAiirE' and JOHN M. RoHLrING,both citizens ofthe `United 4Sta-tes, residing at St. Louis, Mis souri, have invented a certain new and useful Improvements in Log-Cars, of which the following is a full, clear, and exact description, such asv will enable others skilled in the art to which it appertains to malte and use the saine, reference being had tothe accompanying drawings, forming part ofV this specification, in which- Figure l is a' top plan view of a log car constructed inv accordance with our invention; F ig. 2 is a side elevational view of said car; Fig. 3 is an elevational view o f one of i' the holsters or bunks; Fig. 4; is a vertical sectional view 'taken on approximately the line of Fig-3; Fig. 5 is a perspective view of the member from which the bolster is formed and illustrates the way in vvhichl the lower flange of said member is severed;f

and Fig. 6 is a perspective view vof the bolster illustrating the way in which the lower flanges of the bolster member 4are connected to the vertical webof saine.

This /invention relates to cars, and particularly to cars provided withsteel under frames.

The main object of our invention .iste provide a steel log car of novel lconstruction which is strong and inexpensive to manu-.

facture.

Briefly described, our improved log car consists of a single continuous center sill provided at its opposite ends with draft riggings," bunks or bolsters arranged transversely of the center sill and adapted to support a pile of logs, and braces connected to the cent-er sill and to the bunks for reinforcing and strengthening the bunks.

'Referring to .the drawings which illustrate the preferred form of our invention, A designates a continuous center sill which preferably consists of a rolled -beam that extends from end to end of the car. lf desired, however,`t-his center sill could be a built-up structure or a commercially rolled member of any desired shape in cross section. Two 1oolsters or bunks B are arranged .transversely of the center sill, and in the construction herein shown, each of'said blinks consists of a rolled -beain .of greater .depth than the center sill and provided in its vertical web l with an vl-shaped opening y2 tliatnproject beyond same. l, f britte is preferably formed from two mein, lll? through which the center sill passes. Each of the bunks orbolsters B diminishes graduallyl in depth from its center to its outer J ends, as shown inFig. 3, and its topv flange 3 lies in a horizontal plane so as to provide a 6e flat .supporting surface for the logs, each bolster being provided at its opposite ends with. pointed projections 3a connected to the top flange 3 and adapted to forni a fulcruin on wl'iich the logs .can be placed to swing 65 them olf the car.

' To produce a bolster of the construction herein shown, we first partially sever the lower flange of the llbeain from its vertical web l. by vertical cuts l that extend from the 70 outer ends of the beam to points adjacent the middle of the beam, as shown in Fig. l, thus producing a laterally projecting flange 5 on each side of the web that hasV only its central or middle portion connectedto the web. The opposite ends of these flanges 5 are then .bent upwardly and the portion of the vertical web 1 that extends below said4 flanges, as shown in dotted lines in Fig. 6, isl

sheared oli so as to produce an .lf-shaped bol- 8O pairs of angles G for this purpose, the veri tical legs of said angles being riveted to the opposite sides'of the web l and the horizontal legs of said angles being riveted. to the flanges 5, as shown in Fig.

The center sill is connected to the holsters by means of corner irons i arranged at the Junction of the webs of the holsters and centei sill, as shown in Fig. 3, each bolster be- A ing connected to the center sill by four coi' ner irons 7, as shown in dotted lines in Fig.

l. An octagonal-shaped top plate Sis connected to the top flange of each bolster and to the top flange of the center sill, and said plate is bent downwardly on 'each side of the bolster, as shown in Figs. 3 and a in View of 100 the fact that the top flange of the bolster lies in a higher horizontal plane than the top flange of the center sill.

' The holsters are reinforced and vstrengthened by means of an X-shaped brace ar- 105 ranged between the holsters, and also a numbei' of inclined braces 9 connected to the holstersand to theportioiis of the`center sill The X-shaped bers l() arranged on opposite sides of thc-` ccnter sill and bent inwardly intermediate' members 1t) 'are connected to the vertical websof the holsters adjacent the points where the inclined braces 9 are. connected to the holsters so that each bolsterl forms the minor axis of an `approximately diamond-shaped structure whose major axis consists ofthe center sill A. lhe brace members 9 and 1() preferably consist of rolled angles, and the connection between said members and the center sill and holsters is preferably etlected byY shearing oila portions of the horizontal legs ofthe angles and then bending the nntlanged portions of the vertical latcr ally to form integral flanges through which the fastening devices pass. 'lhe members t) and 10 are so arranged that the fastening devices` which connect the members 10 to the holsters also secure the members 9 to lthe bol` sters, the intermediate portions of both members 10. being connected to the center sill by the same fastening devices and the ends of each pair of diagonal braces 9 being connected to the center sill by the same fastening devices., lt will he obvious,however, that our broad idea is not limited to this exact construction as the brace members could he connected to the parts with which they cooperate in numerous other ways.

A center bearingl C is connected to the under side of each bolster and in the construction herein shown each center hearing :oi'isists of a cast member that is provided with a pocket 11 to receive the bolster and )oitions 12 that project laterally from each iide of said pocket to form supports for the :enter sill, said portions 12 being located in i higher horizontal plane than the bottom of he pocket 11, as shown in Fig. 4.

'.lhe portions 12 are substantially channelbape in .cross section so as to embrace the wer flange of the center sill, as shown in lg. 3, and said portions are connected to aid lower flange by fastening devices, the ottoni wall of the pocket 11 also being coniected to the lower flange -of the bolster by Irstening devices. The portions 12 on which te center sill rests are reinforced and :rengthened by means of tapered tia-tiges or ussets 13 that have their inner ends con- '.ected to the side walls 11l of the pocket 1.1. ADraft riggings are mounted on each end the center sill inside of housings conectcd to the center sill, each ofl said housgs consisting of .top and bottom plates 14 hich are fastened to the upper and lower tnges of the center sill, and channel-shaped embers l5 arranged between said top and 'ttom plates on each side of the center sil-l, shown in Figs. .1 and 2. The vertical web esa-,ece

of the center sill is slotted to receive a spring and followers, and stops 16 are connected to the center sill to'coperate with said followers, the draw-bar 17 being provided with a yoke arranged horizontally in the slot in the center and extending around the spring and followers. The top and bottom. plates 14. also form a support for a vertically disposed shaft 18 to which the brake chains, not shown, are connected.

An underframe ofthe construction above described is very strong and can be mannfactured at a low cost, and while we have herein stated that it forms part of a log car', we do not wish it to be understood that it is limited to this use as it could be used as the underframe of various other types of cars.
